The reason for its five discrete
shapes lies in the mathematically calculated rate of flicker generated by precise
placement of a lamp fixture within the rotating cylinder. The user sits or stands
very close to the machine (nose approximately two inches from cylinder), eyes
closed. The flickering light
induces Alpha
waves to defeat Beta waves
normally active in the "awake" brain. By subtly shifting facial positioning
and proximity to the machine, an Alpha range of light interruptions (8-13hz)
opens to the user. Effects of such periodic waves on the human brain vary among
users.
